Learning Rate

Encord Computer Vision Glossary

Learning rate

In machine learning (ML), the learning rate is a hyperparameter that determines the step size at which the model's parameters are updated during training. It is a key factor in the optimization process, and can have a significant impact on the model's performance.

The size of the steps that the optimization method takes to update the model's parameters is determined by the learning rate, which is normally chosen before training starts. The model's parameters may be updated too quickly if the learning rate is too high, which could cause it to overshoot the ideal solution and exhibit unstable or oscillatory behavior. The model's parameters could be updated too slowly if the learning rate is too low, which could hinder convergence and necessitate more training iterations to get the best outcome.

It can be difficult to determine the ideal learning rate for a specific model and dataset, and this process frequently involves some trial and error. One typical method is to experiment with a variety of learning rates and assess the model's performance at each stage to find the best one. The convergence and optimization of the model can be enhanced by dynamically adjusting the learning rate during training utilizing strategies like learning rate scheduling.

Choosing the right value can have a big impact on the performance and convergence of the model, which makes the learning rate a key hyperparameter in ML.
